Through hole resistors are electronic components designed to limit and control the flow of current in an electrical circuit. An example of this type of resistor is the RWR78S1740FSS73. In this article, we will discuss the application field and working principle of this device.

Application Field

The RWR78S1740FSS73 is a through hole resistor with a resistance value of 78Ω and a tolerance of 0.5 %. It has a higher resistance than other types of resistors, such as the axial lead and surface-mount resistors, which makes it ideal for applications involving high power dissipation, such as motor control, server power supplies, and other high-voltage applications. This resistor is also suitable for applications that require ultra-precise resistance measurements, such as medical imaging, instrumentation testing, and robotic control.

Working Principle

The working principle of a through hole resistor is based on the concept of resistivity. Resistivity is a measure of the resistance of a material with respect to the flow of electric current and is associated with the properties of the material itself. The RWR78S1740FSS73 has a resistivity of 78Ω/m, which means that it will resist the flow of current with an impedance of 78Ω. The resistance value of the resistor is determined by the thickness and length of the resistive element.

When voltage is applied to the resistor, current will flow through the resistive element. The current flow is determined by the voltage applied and the resistance value of the resistor. The resistor dissipates the energy of the flowing current in the form of heat, which must be removed from the component in order to protect it from overheating and damage. The size and spacing of the leads as well as the surface area of the resistor all play a role in efficiently dissipating the heat.

Conclusion

The RWR78S1740FSS73 is a through hole resistor with a resistance value of 78Ω and a tolerance of 0.5 %. Its higher resistance and precise resistance measurements make it well-suited for applications that require high power dissipation and ultra-precise resistance measurements. The working principle of the resistor involves the concept of resistivity and the energy dissipated is removed in the form of heat.
